Ye Qin followed behind the veiled girl, opened the protective shield from the cave where the mine collapsed, and walked deep underground against the strong scorching wind. A large red light gradually appeared in front of him. The two of them walked dozens of miles before they landed on the ground.

Glancing around, everything in front of him made him gasp. This is an underground cave, but this cave is far beyond his imagination, surprisingly large. There are even low and undulating mountains, low-lying areas, stone forests, underground cracks, underground rivers, lakes, and deep pools. The scorching waves of air rolled in the rivers and lakes, and immediately the mist steamed. The entire cave was red, and even if he looked into the distance with all his might, he couldn't see the edge.

This underground cave is supported by numerous huge karst columns. Each huge stone dissolution pillar is at least hundreds of zhang high, and dozens of hundreds of people can't surround it, lying in the ground, standing tall in the sky, majestic and magnificent.

These huge stone pillars towering in the cave can support this underground for a world, and bear more than a million pounds. In addition, on the top of the cave, there are countless sharp giant stalagmites standing upside down, which is terrifying. If you drop a stalagmite casually, I'm afraid it's at least dozens of zhang long.

Ye Qin looked back at the way he came, and was shocked to find that he had stepped on a huge inclined stone pillar and walked down. Walking up this karst pillar, you can return to the collapsed hole on the second floor of the cave in Wankuling.

"This underground karst cave is only afraid that it will be tens of miles at least and hundreds of miles at most. It should be regarded as the third layer of the Wankuling Cave. ”

Ye Qin thought to himself.

This naturally formed giant underground karst cave is by no means comparable to the second floor of the cave dug by manpower. If you rely on manpower to dig it, I am afraid that all the immortal cultivation sects in the Lingwu Mountain Range will not be able to dig such an endless underground cave if they dig together for thousands of years.

In the distance of the cave, there is a dazzling river of red magma, rolling and flowing. It is this river of red magma that reflects the entire underground cave in red. The heat wave rolled in, and it only took a while to make Ye Qin sweat.

Although the veiled girl has an ice sword to protect herself, she is inevitably fragrant, the blue shirt is wet, and it is thinly attached to the creamy red skin, and the bumpy figure is faintly visible, which makes Ye Qin's heart pound, he didn't dare to look at it more, and hurriedly turned his head away.

This cave is filled with a strong fire aura, and ordinary plants and beasts simply cannot survive here. But fire-type plants and fire-type demon beasts can not only survive, but also survive extremely well. All kinds of strange flowers and plants and large trees with bowl mouths are almost everywhere. The fire grass with its leaves swaying like a flame, the red iron tree that looked like a red-hot iron branch, and the blood extension tree that was bright red like blood, these spirit grasses could hardly be seen in ordinary environments, and could only grow in geothermal places where fire and spiritual energy were abundant.

Ye Qin's feet rustled, he casually picked up a red stone from the ground, and found that it was a fire-type red ore, which could be used to create a fire-type spirit weapon or even a magic weapon after refining.

Ye Qin couldn't help but swallow his saliva, his eyes lit up.

If you pick up a small stone on the ground, it is all fire ore, and there must be a huge fire ore deposit underground. With such a huge amount of mineral wealth, after the various immortal cultivation sects came here, it was strange that they would not fight desperately to grab it. However, no sect of immortal cultivators could swallow such a huge cave alone, and in the end, they still had to join forces to divide it.

The girl in the veil was also holding a piece of fire-based ore at this time, pinching it, feeling the fire-based breath in the ore, and whispered to herself in surprise: "What Dad said is really good, this cave is really full of fire-based ores, and you will definitely be able to find the best fire-based ores suitable for quenching fire-based flying swords here." ”

She looked in all directions of the cave.

The view here is not very good, the fog is too heavy, red and cloudy, if the two of them are separated by dozens of feet, they can only see a human silhouette. If you are hundreds of feet away, you can almost only see a very dim shadow.

The most conspicuous thing in this underground is the towering megalithic karst pillars, and the red magma river in the distance. The river of red magma was estimated to be more than ten miles away from them, but its red light was extremely dazzling in the cave, so they could see it clearly.

The veiled girl didn't hesitate any longer, and rushed towards the red magma river. For the various types of fire ores on the side of the road, whether they are low-level or high-level, they don't bother to take a second look. Such low-grade ore didn't do much to her.

Ye Qin was extremely depressed. He still didn't understand what this Imperial Sister wanted to do when she came here. Looking at the look of the veiled girl, it seems that she has already understood the situation here, and has a strong purpose, what she wants to find.

But he couldn't ask.

The only thing he knew was that the purpose was certainly not for him. There are eight thousand disciples of the Qi Refining Stage of the Qingdan Sect like him, and he is not qualified to enter the eyes of this Qingdan Sect senior sister.

He was able to follow this Qingdanmen senior sister to act together, and most likely this senior sister took him with him for the sake of saving her life.

Ye Qin thought, hesitated slightly, and followed. After all, it is definitely better for two people to walk together than to be alone. In case of danger, it can be shared. When you encounter benefits, you can also get a little light. You can't come to this underground for nothing.

On the way, they occasionally encountered this underground demon beast, and the third-order flame wolves roared through the bushes not far from them, as if chasing their prey. Several fiery eagles circled above their heads, shocking them both, and they could only dodge through the trees, trees, and stones.

This underground demon beast is so powerful that people are stunned. There are almost no first-order and second-order weak demon beasts here. Most of them are third-order demon beasts, and a few are fourth-order demon beasts. The third-order demon beast is equivalent to a high-level monk in the Qi refining period, while the fourth-order demon beast is already a low-level monk in the foundation building stage.

That is to say, in this underground cave, any encounter with a demon beast will make ordinary low-level and middle-level monks in the Qi Refining Period flee in embarrassment, and only high-level monks in the Qi Refining Period can barely resist it. If you encounter a fourth-order demon beast, just run for your life, without a large group of Qi refining period cultivators joining forces to besiege it, don't even think about hurting its fur.

It is no wonder that the miners who mined in Wankuling thousands of years ago died so simply, and few escaped. You must know that mining is a great delay in cultivation, and the miners who will mine in the mine are usually not too high in cultivation, they are all low-level in the gas refining period, and a very small number are in the middle level of the gas refining period, purely to earn spirit stones, and they will only go to mining if they are forced to do so.

Ye Qin's mouth was a little dry, and he didn't know if it was because the underground was too hot, or because he saw a powerful demon beast running all over the ground in this cave.

However, for Ye Qin and the veiled girl, the fourth-order demon beast was not a big threat to them.

They were all the top cultivators of the ninth layer of the Qi Refining Period.

The Veiled Maiden possessed a set of magic weapons with extremely strong attack power, and her strength far exceeded that of ordinary Qi Refining Stage cultivators. Alone, it was enough to kill any third-order demon beast, or barely resist a fourth-order demon beast.

Ye Qin didn't have the best magic weapons, so he took out several garbage magic weapons casually, which was more than enough. Although the strength is not to the point where this senior sister is as perverted, it is not comparable to ordinary Qi refining stage cultivators.

When he encountered a third-order or fourth-order demon beast, even if he couldn't kill it, he still had enough power to protect himself and escape.

Now they should be the first few monks to enter the cave, and it is the best opportunity to search for the cave before the large number of monks enter the cave. The good things in this underground cave are definitely on a first-come, first-served basis, and no one will be polite

About an hour after the two of them left the entrance. Three Beast Spirit Sect trial disciples dressed in colorful and green costumes, monks of the eighth and ninth layers of the Qi Refining Period, appeared at the collapsed place. They were stained with dried, black blood, or exhaustion and scars. It seems that they have either hunted and killed others, or they have been hunted down by others.

The three monks cautiously looked at the collapsed hole, and after finding that there was no danger, they followed the huge stone column and entered the cave. They were stunned by this majestic underground cave for a long time.

These disciples of the Beast Spirit Sect have experienced life and death along the way, and they can pass through the second layer of the cave and mine road to this underground cave, and almost all of them have become elite monks. The surprise on their faces didn't last long. A man with a gloomy expression at the head gestured to the two Beast Spirit Sect monks behind him, and immediately led them to hide in the red mist and ambushed near the giant stone dissolution pillar.

Then, half an hour later, four or five yellow-shirted monks from a small sect hurriedly appeared at the collapse of the second-floor mine tunnel in the cave, and soon, they came to this cave along the huge stone karst pillar.

Just when they were shocked by the cave, their spirits were the most relaxed moment.

A sharp flash of light suddenly appeared, shooting towards one of the yellow-shirted monks in the front. The yellow-shirted monk's face changed, and he hurriedly turned around to dodge, but he still didn't have time to completely avoid the sharp light, and let out a miserable cry of "Ah!" from his mouth. One arm was slashed by a spirit knife, and almost the bone was shattered.

The man in the yellow shirt was also tough enough, and after being so seriously injured, the painful green tendons burst out, and he almost bit off the steel teeth, but he was still very conscious, and shouted: "Sneak attack, kill!" The spirit knife in his hand slashed towards the incoming Beast Spirit Sect disciples.

"Gaga, you miscellaneous people have been chasing and killing Lao Tzu for a long time, and now it should be often Lao Tzu's power. Let's die to Lao Tzu!"

A grim-looking man in green emerged from his hiding place like a ghost and pounced on the monks. He was holding a flying knife in his hand, and there was a long silver silk thread at the handle of this flying knife, and it was by this silver silk thread that he controlled.

The other two Beast Spirit Sect disciples released the two large demon beasts in the beast bag, the Demon Tiger and the Demon Leopard, and pounced at the same time. The seven male and female monks of the two sects immediately fought and fought together

Just when the three Beast Spirit Sects and the four or five monks of a small sect were not tired, they were engaged in the final battle at the entrance of the cave.

Ye Qin and the girl in the veil also encountered the biggest crisis after they entered the cave. After entering the cave, they carefully sneaked along the way, trying to avoid the monsters and monster lairs along the way. But he still accidentally broke into the territory of a demon beast and was targeted by this demon beast.

A red shadow, silently fanning its wings, flew at a low altitude, wandering, and suddenly it swooped down behind Ye Qin like lightning.

Ye Qin had already been highly vigilant around him, how could he be easily pounced, his heart was cold, and a little under his feet, he disappeared from the spot strangely, and when he reached three zhang away, he avoided the red shadow that rushed from behind him with a fishy wind.

At the same time, the soul bell he had already prepared, flicked his fingers, and with a "bang", a silent but powerful wave swept towards the red shadow. The red shadow had never seen such an attack before, and was suddenly stunned and fell to the ground.

After standing still, Ye Qin looked at the red shadow in a relaxed manner.

It was a two-winged and two-legged demon snake with a head and a foot tall, and it looked like it should be a third-order demon snake. This demon snake has red spots all over its body and is covered with fine scale armor. It rolled on the ground in a daze, then jumped up, stood on its feet, flapped its wings, and spewed out some red poisonous mist with its tongue, and its scarlet snake eyes stared at Ye Qin angrily, as if it was annoyed that it was stunned by Ye Qin and fell to the ground just now.

Ye Qin's heart sank, this third-order demon snake was actually stunned and blinked in the blink of an eye, and then he came to his senses, but he was afraid that it would be difficult to deal with.
